NA: not applicable. ^aPopulation samples obtained at 3- and 6-month post-IRS from the study MRP ecotope. Population samples obtained between pre-IRS and during IRS from the study MRP ecotope as the Anopheles sampling site II^b, and additionally, other Anopheles sampling sites of Bo Rai district^c. ^dAbbot’s formula applied to correct observed mortality in the test.
